9 Claims.

This invention relates to a portable wall paper paste applicator.

The primary object of the invention is to provide a device of this character which is inexpensive, simple in construction, and easy to operate.

A further object is to providea device of this character by means of which paste may be quickly and uniformly applied to wall paper in acontinuous, smooth layer of uniform regulated thickness.

A further object is to provide a device of this character whichis light in weight and small in size whereby it may be carried about easily and installed or conditioned for use quickly by simply placing it upon a table or other support.

A further object is to provide a device of this character by means of which paste may be flowed upon a predetermined portion of a strip of wall paper Without danger of excessive lateral flow around the edges of the paper.

A further object is to provide a device of this character by means of which a paste may be flowed upon paper evenly and without lumps.

Other objects will be apparent from the declaims. the drawing: J Fig. 1 is a vertical transverse sectional view taken on line ll of Fig. 2.

Fig. 2 is a top plan viewdrawn on a smaller scale than Fig. 1. f

Fig. 3 is a fragmentary detail sectional View taken on line 3-3 of Fig. 2 and on the same scale as Fig. 1.

Referring to the drawing, which illustrates the preferred embodiment of the invention, the number I 9 designates the top of a Work table upon which is mounted a member H, such as a glass plate, which has a smooth surface,- and which may rest upon pads I2.

The paste applicator is adapted to be loosely and removably mounted upon surface plate II, and comprises a pair of parallel end members or walls E3 of similar size and shape. End members I3 are interconnected by inclined downwardly converging cross members or side walls l4 and G5, which are spacedapart at 'theirjl'o wer edges thumb screw l9 may be adjustably positioned for the purpose of holding one end of the applicator at desire-d'elevation above surface -plate H. The opposite'end of each of the end members [3 has a downwardly projecting portion defining a shoulder 2! adapted to bear against an edge of table top 13., The last named end portio-n' is generally downwardly tapered, and a notch or recess 22 is formed therein at a'level below the plane of the portion of the bottom edge of said member adjacent the paste trough.

Inclined cross member l4 terminates in a lower edge substantially flush with the lower edges of the adjacent portions of end members 13. The lower end of cross member I5 is defined by a vertical edge. A bar 23 -of substaritiallyinVeited L-shape in cross'section is secured to the lower end of cross member 15 by bolts 24. A spreader strip 25, formed of felt, rubber or other yielding or flexible material, is clamped between the lower edge of cross member 15 and the bar 23. Strip Z5 proj'ectsaslight distance below the level'oi the lower edges 'of end members 'I3. The bottom edge 26 of bar 23 is preferably inclined downwardly at a slight angle toward the spreader strip relative to the bottom plane of the device. The bar 23 is spaced from the lower portion 'of cross member I4 'sufficiently to provide a wide mouth for free A block 27 is secured to each end member I3 between cross members I4 and I5 at the mouth of the trough. These blocks 21 define the ends of the mouth of the paste trough. The bottom face 28 of each block Z'I'inblines outwardly and downwardly at a slight angle relative to-the bottom plane of the'de'vice.

A block 29 is secured on the outer face of each end member 13 and mounts a set screw 30 which is positioned slightly forwardly of the shoulder 2|, whereby it rests upon thesurface'plate H to support the side of the trough opposite the spreader 'at a desired elevation relative to said surface plate.

In use, the device is mounted on surface plate II as shown in Fig. 1 by simply :placing it upon said plate with shoulder 2| engaging a'n'edge of table In. This simplicity of mounting, eliminating need for brackets, platforms, etc, and also eliminating manipulation oflpart's, is one of the such that the sewage edges of the paper pass beneath blocks 21. The set screws I 9 and 30 are then adjusted to position the device at a proper elevation to permit the paper to pass free- H, as illustrated in Fig. l.

- Fig. ,1. prises an elongated bar 35 and a handle 31. Bar

" 36 is preferably of' a cross sectional configuration I asillustrated in Fig; 1 to fit snugly the mouth f the trough, ,as in a generally wedged relation, H

ber 35 may be positioned within the trough resting upon the upper edgeof bar 23 with handle I 31 resting against cross member l5 when the de- 21 and trough member M, the device is positioned at a slight inclination relative to the surface'plate The inclination of the bottom faces 28 of blocks 2'! permits outa ward flow of paste to a limited extent below said blocks, to insure'application of paste to the full widthof the design-bearing portion of the paper,

and including limited application to the selvage margins of the paper, but not extending tothe edges of theweb. Thus the flow of paste to the design-bearing lower face of the paper is avoided.

The clearance between the paper web and the spreader is also limited to prevent normal free flow of the paste thereunder. The operation of paste application normallyentails adherence of paste to the paper while passing below the mouth of the trough, with the adhesion so efiected being sufficient to retain a layer of paste on the paper as the paper isLpulled beneath the spreader, even though the pastejwill not flow freely beneath th spreader when the paper is stationary.

It will be observed that the operator need only 'pull on the end of the paper web, once the device 'has been adjusted properly, and" the paper, will unroll and pass beneath the applicator for proper uniform application of paste thereto. The device is held stationary by the engagement of shoulder 2| with the table edge while the paper is being pulled. When paste has been applied to a portion of required length, the same'may be cut;

trimmed and applied, without requiring operation or manipulation of the device. the device automatically retains paste therein and V prevents undesirable flow or leakage of paste for short periods of time if the paste is of r the".

proper heavy or thick consistency. Hence, the operator neednot 'give the device his constant careful attention, and is free to perform the operationsof cutting and trimming the paper and applying it to the wall, while leaving the device unattended. a

The provision of a wide discharge mouth is with the paper, and also to permit absorption of lumps which may exist in the paste. The lump In other words.

or plastic, with equal facility and without changes other than such obvious changes as are permitted or occasioned by the nature of the' material employed. Among such changes may be the formation of parts 21 and 29 integral with end walls I3.
